Using Shock Cord to Pull Lazy Jacks Outward
We recommend shock cord to hold Lazy Jacks open to make it easier to raise sail.
1. Attach shock cord to the end of the lower spreaders. Hog rings work well for this
purpose. Use rigging tape over hog rings.
2. Temporarily tie other end of shock cord to Lazy Jacks at a length that holds Lazy
Jacks out, yet will not be too short and damage spreaders when boom is swung out.
3. Test length by swinging boom all the way out. If necessary, lengthen shock cord
before permanently attaching to Lazy Jacks.
Mounting Cradle Straps
(Make sure you’ve checked sail containment before mounting eyestraps.)
Pull aft line towards end of boom until line intersects with mark you have made as
indicated in chart B. The eyestrap will be located aft of mark. See below.
